兴安落叶松、白桦树皮厚度与胸径关系研究

Relationship Between Bark Thickness And Diameter At Breast Height Of Larch And Birch In Xingan

兴安落叶松(以下简称落叶松)和白桦是大兴安岭林区的主要树种,蓄积量占80%以上,树皮是栲胶工业的重要原料。另外白桦树皮还可以入药,提取桦皮油,制作各种工艺品。因此,研究树皮厚度(以下简称皮厚)与胸径的关系,建立数学模型,就可以为预测树皮产量提供依据。

Xingan Larch （hereinafter referred to as the larch and birch） is the main tree species in Daxing＇ an Mountain forest area. The volume accounted for more than 80% and the bark is an important raw material for in- dustrial tannin. In addition the birch bark can also be used as medicine, extraction of birch bark oil, the produc- tion of handicrafts. Therefore, studying on the bark thickness （ hereinafter referred to as Pihou） and DBH relation- ship establish the mathematical model, it can provide the basis for the prediction of bark yield.
